white noise

名詞

不可算名詞 広義

(physics) A random signal (or process) with a flat power spectral density; a signal with a power spectral density that has equal power in any band, at any centre frequency, having a given bandwidth.

日本語の意味

物理学において、全ての周波数帯域に対して均一なパワースペクトル密度を持つランダムな信号。すなわち、指定された帯域幅内の任意の中心周波数において等しいパワーが分布している雑音。

In the lab, we modeled white noise as a random process with a flat power spectral density to test the filter.

実験室でフィルターをテストするために、フラットなパワースペクトル密度を持つランダム信号を確率過程としてモデル化しました。

意味（1）

(physics) A random signal (or process) with a flat power spectral density; a signal with a power spectral density that has equal power in any band, at any centre frequency, having a given bandwidth.

Conventional statistical analyses presuppose that intrinsic variability is white noise. White noise yields a jagged and irregular line with a fractal dimension of 1.5, because successive observations are statistically independent of each other.

意味（2）

(nontechnically) Any nondescript noise used for background or to mask or drown out other noise.

意味（3）

(by extension) Speech that goes ignored or uncomprehended.

The rest was white noise; I was sick of listening to who I was supposed to be.
